In France, around 70% of small and medium-sized enterprises use a CRM, with adoption exceeding 90% once a company employs more than 10 people (source: Belacom). It is well understood that the value of a CRM lies in its ability to deliver a 360° view of customer interactions across all channels and to provide reliable data. This is even more true with AI, which now scans these data to extract all their value.
The interconnection between communications tools (telephony, collaboration, videoconferencing, contact center) and customer relationship management systems is therefore vital. Their convergence supports and shapes the digital transformation of the customer relationship within a business.
Yet, the evolution of contact center environments and CRM solutions is accompanied by a notable diversification of the interconnection modes now available to companies. The aim of this article is to present these main interconnection modes in a simplified way, grouping them into four categories arranged by increasing implementation complexity.
CTI is dead, long live CTI!
CTI (Computer Telephony Integration) is an old acronym that appeared in the early 1990s when companies sought to link two previously independent worlds: traditional telephony and desktop computing. The objective was to boost productivity in call center or customer support environments. Its main feature was to display caller identification on incoming calls.
But forget the 90s CTI image: today, it’s a cloud toolbox that boosts agent productivity. If the acronym still nods to its technical origins, its uses and the technologies behind it are now far closer to cloud software than to traditional telephony hardware.
With the advent of IP telephony and cloud environments, CTI has been enriched with new features: integration (not just coupling) with CRMs, click-to-call, automatic call distribution (ACD), voicemail transcription, advanced statistics, or even omnichannel integration that enables managing voice, messages, and emails in a single interface.
Despite these strong technological advances, many vendors keep using the term “CTI.” For example, at ISI-COM, the founder spoke of it as early as 1996 and made it a pillar of the company’s strategy. But talking about CTI at this publisher today connotes a multi-technology toolbox intended for developers.
CTI features no longer stop at caller identification or click-to-call. They are expanded, for instance at Akio, to include intelligent routing, recording, transcription and call summarization, or even anonymization functions for sovereignty concerns.
The shelf-ready connector: simple, quick to deploy, but scalable at its own pace
In a sense, CTI was the market’s first connector. If it laid the foundations for interconnection, the native connector democratized access.
The native connector — also known as shelf-ready or “out-of-the-box” — is often the preferred entry point for companies that want to interconnect their tools and optimize their operations. It enables, in just a few clicks, to link a voice solution or a contact center platform to a CRM to streamline the agent’s journey without undertaking major IT work.
This type of connector is attractive for its ease and speed of deployment, but — like CTI — it offers limited customization options or sophisticated automation. Its simplicity can also become a trap (vendor lock-in, lack of flexibility for specific business needs).
Nevertheless, the features range from the most common to the more advanced depending on the connectors: automatic call logging, contact synchronization, creation of tickets or opportunities, sending SMS, etc. This functional scope of a connector evolves regularly, in line with market expectations, technology developments, and the editor’s available resources.
Thus, Telavox recently strengthened its integration with Zendesk by adding advanced workflow automation, BankID identity verification during calls (for regulated sectors), and the logging of mobile calls for remote work.
The Rise of Marketplaces
If their terminology varies — Apps Store, App Gallery, AppFoundry marketplace for Genesys, App Directory at Enreach, Rainbow Hub at ALE, Integration Directory for Eloquant, etc. — all editor marketplaces for multi-channel communication solutions now multiply connectors to CRM platforms. To name the historic French actor Genesys, its AppFoundry features nearly a hundred connectors in the “CRM & Case Management” category.
Most often, the referenced CRM leaders include Salesforce, HubSpot, or Dynamics (estimates vary; these two players account for about 35% to 40% of the market in France). The presence of other solutions depends on the publishers’ strategies and their market positioning.
Note that this article mainly concerns connectors published by the editors of communication solutions. Marketplaces may also feature connectors developed by partners or integrators (see the API section). For example, 3CX’s Sellsy connector was developed by Sellsy; similarly, for Genesys, the Zoho connector was developed by its partner Softphone.ai; or connectors developed for HubSpot, Dynamics, or Zoho CRM by partners of Amazon Connect.
The webhook: for no-code and agile automation
If native connectors offer turnkey solutions, webhooks enable deeper automation without bespoke development. Let’s see how.
A webhook is like a tiny, invisible trigger (the “trigger,” as English speakers say) that revolutionizes automation without writing a single line of code by allowing two different applications — here a CRM and a communications platform — to talk in real time, with no human intervention. For example, as soon as a new call arrives, a message is automatically sent to the CRM to alert it, and the CRM can then act accordingly, such as creating a new contact record or adding a note to an existing one.
Odigo offers automated call qualification, dynamic routing, and information retrieval via webhook to any CRM. Likewise, Heedify facilitates the integration of its contact center solution with Salesforce or Microsoft Dynamics via Power Automate, enabling workflows and displaying the customer file at each call, without custom development.
Automation via webhooks provides a middle-ground solution for extending integration. It remains lightweight, agile, but can also show limits for more complex journeys.
An omnipresent interconnection mode within automation platforms
Automation platforms (or “hubs”) like Zapier, Make, IFTTT or Power Automate offer a no-code / low-code approach that enables individuals to create automated flows between a communications platform and a CRM. One notable difference is their vendor-agnostic stance. They connect hundreds of applications, but use at scale can become costly and less suitable for real-time integrations.
Make.com, for instance, is compatible with most major VoIP, UCaaS and CCaaS solutions, either via direct connectors that Make calls “official modules” (Aircall, Diabolocom, Ringover, Teams, Zoom, RingCentral) or via open APIs (Genesys, Kiamo, Mitel, Avaya, 3CX, Wildix, Wazo, Enreach, Dstny, Telavox, Akio, Axialys, Eloquant, Heedify). The connectors mask the API complexities by offering truly no-code use and ensuring security (preconfigured OAuth). We will revisit the API question in the article’s final chapter.
When no-code / low-code integrates CCaaS solutions themselves
While relatively open, agnostic, and offering appreciable no-code / low-code ergonomics, third-party automation platforms have an intrinsic drawback tied to their mode of operation: they require exporting often sensitive data to a third party.
Whether for trust, security, or regulatory compliance reasons, more and more publishers have therefore developed CRM interconnection modules directly integrated into their solutions.
At Akio, for example, URL or toolbox technologies allow users to create their own connector within the platform. The module is CRM-agnostic. The same logic applies to the toolkit developed by Diabolocom, which enables simply integrating the platform’s features into a third-party CRM.
The API era and CPaaS: toward programmable and tailor-made integration
If webhooks and automation hubs simplify interconnection, their capabilities remain limited to predefined scenarios. For companies facing complex or evolving customer journeys, APIs and CPaaS platforms offer greater flexibility, but require manually configuring many technical parameters; they thus demand a minimum level of technical understanding.
An API (Application Programming Interface) enables dynamic bridges between systems, far beyond the simple notifications of webhooks. For example, an API can synchronize in real time the data of a call with a CRM, trigger advanced workflows (such as sending a personalized SMS after an interaction), or integrate features like automatic transcription or sentiment analysis.
Unlike native connectors, APIs adapt to specific business processes, but their implementation requires technical expertise and a substantial budget.
CPaaS platforms (such as Twilio, Vonage or 8×8) take things a step further by offering turnkey environments to design multi-channel communication experiences. They natively integrate voice, SMS, video, chatbots and even AI, without heavy development. For this reason, they target organizations looking to innovate and scale their integrations.
For example, a company can use Twilio Flex to unify its channels of communication (calls, chats, emails) into a single interface connected to its CRM, while automating tasks such as ticket creation or sending confirmations.
CPaaS platforms thus shorten deployment times, but their cost and complexity can pose a barrier for smaller organizations. The risks in terms of maintenance, dependence on developers, or vendor lock-in are not inconsequential either.
What is certain is that the API-first model and the rise of CPaaS platforms like Twilio, 8×8, Sinch, Vonage, Amazon Connect or RingCentral enable companies to orchestrate bespoke synchronization and control of all their customer relationship channels.
The particular case of Orange Business’s OCF connector
In an increasingly complex technological environment, solution integrators and IT service providers are regularly called in on a project basis to implement bespoke interconnections.
Orange Business — the integrator/IT services arm of Orange — has positioned itself in this niche with a more industrial approach by developing OCF, a universal connector. Certified on more than 100 applications, this connector illustrates an agnostic integration strategy capable of guaranteeing interoperability between any telephony solution (IP-PBX, ToIP, cloud) and leading or sector-specific CRMs.
No single choice, but a hybrid logic at the service of company priorities
Behind this panorama, one truth stands out: The range of interconnection modes has never been as wide or as mature: from plug-and-play connectors to API-driven CPaaS platforms, via the agnostic CTI and event-driven automation.
But choosing is not merely a technical or IT question; it is a strategic decision. Business maturity, investment capacity, IT lifecycle, and the pressure on the security of data flows more reliably define the right model than any comparison sheet. It is ultimately the company’s priorities, the nature of its customer journeys, and the ability to maintain a balance between ease of use and scope of functionality that guide the trade-offs.
All the models presented here are intended to coexist on the market, with each organization expected to build its own integration path in response to its specific challenges and to the evolution of its environment.
No model is universal: the right choice depends on your priorities — business maturity, budget, security — and your ability to mix solutions. The future? An intelligent hybrid where the contact center handles real time, and the CRM capitalizes on customer knowledge. It’s up to you to craft your equation.

Avertissement
The article relies on a methodological stance: it starts from the communications platforms to explore the integration models they offer. A similar exercise starting from CRM platforms would be instructive but is not the purpose of this article. The information presented comes from interviews with the publishers who responded to our inquiries, from exploring their websites and marketplaces.
The list of CRMs is not exhaustive and relies on the major players marketed in France.
